PUMPING APPARATUS.

Application filed August 5, 1918.

To all w hom it may concern.'

Be it known that 1, WILLIAM S. BAR- NICKEL, a citizen of the United States, residing at St. Louis, a certain new and useful Improvement in Pumping Apparatus, of which the following is a full, clear, and eXact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to apparatus of the type that are used for simultaneously pumping two or more streams of liquid of different Volumes.

One object of my present invention is to provide a pumping apparatus of the general type referred to which is so constructed that it can be adjusted easily to vary the volume of one of the streams of liquid without varying the Avolume of the other stream or streams pumped by the apparatus.

Another object is to provide a pumping apparatus ot' the general ltype referred to which is so constructed that it can be succersfully used for simultaneously pumping two streams of liquid, the volume of one of which is ininitesimally small as compared with the volume of the other stream.

Another object is to provide a pumping apparatus of the kind referred to which is so constructed that the means which pumps the small stream can be adjusted easily while the apparatus is in operation so as to increase or diminish the volume of the small stream without interfering with or changing the operation of the means that pumps the large stream.

Another object is to provide a pumping apparatus that consists of a proportional pump and a main pump combined in such a` manner that the operating medium used to actuate the main pump is also used to actuate the proportional pump, and furthermore, is controlled solely by the governing device on the main pump that controls the supply of operating medium to said main pump.

And still another object is to provide a proportional pump of novel construction that can be easily combined with various types of pumps operated by steam or other eXpansible mediums without mechanically connecting the piston of the proportional ump with the piston or other moving part of the pump with which it is combined.

Specication of Letters Patent.

Missouri, have invented Patented Apr. 19, 1921.

serial No. 248,423.

Other objects and desirable features of my invention will be hereinafter pointed out.

Figure 1 of the drawings is a perspective view of a multiple stream pumping apparatus constructed in accordance with my invention; and

Fig. 2 is a vertical sectional view ofthe proportional pump and part of the main pump with which it is used.

My apparatus can be used in numerous arts for ian-:lling various kinds of liquids, but it is particularly adapted for use in an oil treating apparatus of the kind described in m pendine application Serial Number 248,422, filed i ugust 15, 1918, owing to the fact that it is capable of drawing an ininitcsimally small quantity of liquid from a source of supply and introducing it into a relatively great quantity of liquid that is drawn from a separate source of supply. It is also particularly adapted for use with an oil treating apparatus of the kind referred to, owing to the fact that the proportional pump which forms part of my present apparatus is of such design that it can be easily hooked up with or combined with pumps of the kind generally used in the oil fields for pumping oil through pipe lines. Vhile I have herein illustrated my invention embodied in an apparatus provided with means for pumping two streams of liquid of different volumes, I wish it to be understood that it is immaterial, so far aS my invention is concerned, whether' the apparatus is constructed to handle two streams or more than two streams.

Referring to the drawings which illustrate the preferred form of my invention,

A designates a pump that l will designate as the main pump and P designatesI a proportional pump that is combined with the main pump A in such a manner that the operating medium used to actuate the pump -it is also used to actuatc the proportional pump B, and furthermore, governed by the device on the pump that controls the admission and exhaust of the operating medium to and from the operating cylinder of said main pump A. The pump A preferably consists of a duplex steam pump that comprises operating cylinders 1, pumping cylinders 2, a steam chest 3 provided with a D-valve of conventional form for governing the admission of steam to and from the operating cylinders and a valve casing 4 provided with two sets of inlet valves and exhaust valves, said pump A being used for drawing a stream of liquid of relatively great volume from a supply tank 5 through an inlet pipe 6 leading from said supply tank to the inlet of the pumping cylinders oi" the pump A and then Vlorcing said stream through a discharge line 7. The proportional pump B is ot the same general construction as the main pump A, but it is infinitesimally small as compared with the pump A. For example, the proportional pump can have a l inch bore and a 2% inch stroke and the main pump A a 6 inch bore and a 10 inch stroke. The respective sizes of the pumps A and B, of course, are immaterial, but the point that I desire to emphasize is that the proportional pump may be made smalllenough so that it will handle only a fraction'ot the quantity of liquid handled by the pump A.

The proportional pump B comprises an operating cylinder 8 provided with a piston 9, a pumping cylinder 10 provided with a, piston or plunger 11 which is connected by means of a rod or stem 12 to the piston 9 ot the operating cylinder' and a valve casing 13 mounted on the pumping cylinder l!) and provided with a pair of inlet valves 14 and a pair of discharge valves 15, said valve casing having an inlet pipe 16 that leads from a supply of liquid and a discharge pipe 17 that leads to the inlet pipe G through which the liquid from the supply tank 5 is drawn into the pumping cylinders of the main pump A. The opposite ends of they operating cylinder 8 of the proportional pump are connected by means 'of pipes lu and 18a to the opposite ends of one ol' the operating cylinders 1 of the main pump so as to cause steam to be admitted to ani exhausted from the operating cylinder S et' the proportional pump when steam is al mitted to and exhausted from the opposite ends of the operating cylinders ol" the main pump A by means of the D-valve arranged in the valve chest 3 of the main pump, Bj; combining the proportional pump B with the main pump A in this manner l obtain simultaneous operation of both pumps without the aid of any mechanical connection between the pistons or other moving paris of the pumps. Furthermore, I insure a uniform quantity of liquid being drawn inte and discharged from the pumping cylinder of the proportional pump at each cycle of operations of the apparatus, which quantity ot liquid bears a certain definite or fixed relation to the quantity of liquid handled by the main pump A at each cycle of operations of the apparatus. In order that the apparatus may be adjusted so as to vary the size or volume of one of the streams handled by the apparatus without varying the size or volume of the other stream, I

have provided the proportional pump with an adjustable means that can be set in various positions so as to increase or decrease the stroke of the pistons in the operating cylinder and pumping cylinder of the proportional pump Without changing the stroke of the pistons in the operating cylinders of the main pump A. Said means preferably consists of an adjustable stop 19 that projects inwardly through a stuiiing box in the head of the operating cylinder 8 of the proportional pump B, said stop being adjustably mounted in a yoke 2() mounted on the head of the cylinder 8. By adjusting the stop 19 inwardly the stroke oi the pistons in the operating cylinder and pumping cylinder of the pump B can be reduced so as to diminish the quantity of liquid drawn into and discharged from the Jumping cylinder of the proportional pump at each cycle ot' operations of the apparatus. and by moving said adjustable stop in the opposite direction the stroke of said pistons can be increased so as to increase the supply ot liquid drawn into and discharged from the pumping cylinder of the proportioned pump. A means of the construction above referred to for varying the volume oi1 the stream ot liquid handled by the proportional pump is of simple design; it is etiicient and it enables the proportional pump to be adjusted while the apparatus is in operation. It is, ot course, obvious that any change in the adjustment of the proportional pump has absolutely no effect on the quantity oic liquid handled by the main pump A.

When the apparatus is in operation the main pump A will draw a definite quantity of liquid from the source of supply contained in the tank 5 at each tions of the apparatus, and the proportional pump will draw a definite quantity ol' liquid through the supply line 16 and intrmluce it into the stream of liquid ioxving through the discharge pipe G leading Vfrom the supply tank lf the position ot the stop 19 is not changed the volume ol the two streams handled by the main pump A and the proportional pump B will remain consta ut. thereby causing a definite quantity ot liquid from one source oi supply to be introduced into a definite quantity of liquid drawn from a separate source ot supply at each cycle ot operations ot the apparatusf It' it is desired to vary the volume or the quair tity ot liquid handled by the proportional pump B either to increase or diminish same, this can be effected easily by simply adjusting the stop 19 in the proper direction, and fur? thermore, without the necessity of shutting down the apparatus while the adjustment is being made. It is, of course, immaterial whether or not the discharge pipe from the proportional pump leads into the inlet pipe through which liquid is drawn into the cycle ot operajV llU pumping cylinder of the main pump, as my broad idea consists of a proportional pumping apparatus provided with independentlyoperating means, actuated by the same operating medium, for simultaneously pumping two or more streams of liquid from the same or from different sources of supply. The relative capacities of the main pump and the proportional pump are, of' course. immaterial, but one desirable feature of a pumping apparatus of this construction is `that the means which handles one of the streams can be inlinitestimally small as compared with the means that handles the other stream. Consequently, the apparatus herein illustrated is particularly adapted for use in an oil treating apparatus of the kind described in my pending application previously referred to, owing to the fact that it is sometimes necessary to mix the treating solution with the oil being treated in proportions of about six barrels of treating solution to one thousand or two thousand barrels of oil. Another characteristic of the proportional pumping apparatus herein illustrated which makes it particularly adapted for use with an oil treating apparatus, is that the proportional pump B can be easily cornbined with or hooked up with pumps of the kind that are generally used in the oil ields for forcing oil through pipe lines, owing to the fact that there is no mechanical connection between the pistons or moving parts of the respective pumps. The pipes 18 and 18a that connect the operating cylinder 8 of the proportional pump with the opposite ends of one of the operating cylinders of the main pump are preferably pro` vided with valves 18", so as to enable the proportional pump to be cut out of service in case it is desired to use the main pump independently of the proportional pump. The horizontal branches of said pipes are also provided with drain cocks 18, as shown in Fig. Q, so as to enable the cylinders of both pumps to be drained when the apparatus is not in use.

Having thus described my inventioiuwhat I claim and desire to secure by Letters Patent is:

1. A pumping apparatus, comprising a reciprocating proportional pump provided with means for enabling the volume or quantity of the stream pumped by same to be increased or diminished, a main pump of the reciprocating type, and conduits separate and distinct from the supply and exhaust pipes of said main pump that lead from the opposite ends of the cylinder of said proportional pump to the corresponding ends of the cylinder of the main pump.
